Abstract:
Limiting the ingress of water and aggressive ions such as chlorides is fundamental for the durability of concrete structures. The most significant factors are water-cementitious material ratio (w/cm), appropriate use of supplementary cementitious materials, and unit water content. Concrete mixtures should be evaluated using test methods that bear some relation to the anticipated exposure conditions. In this article—which is based on two articles featured in HPC Bridge Views and a chapter that will be included in the next revision of ACI 201.2R—some of the current, standard test methods for evaluating transport properties in concrete are discussed.
